apply a force to the dispenser tending to slide it laterally over thesurface upon which the dispenser rests. The upward pull may be resistedsolely by the weight of the dispenser which if made heavy enough willresist the force necessary to unwind the tape from the roll. Preferablythe distribution of weight in the dispenser should be such that the lineof upward pull in withdrawing the tape passes through or near the centerof gravity of the dispenser.

in resisting the upward pull. Furthermore even if a quick upward pull onthe tape should momentarily lift the dispenser it would tend to fallback to the same position which it occupied before being lifted.; Thiswould obviously not be the. case if the tape were pulled laterallybecause then the dispenser would be moved from position. With anupwardpull' in line with the center of gravity, a moderate weight issufficient to resist the tension necessary to unwind the tape from theroll. I have found that when using an ordinary half inch. cellophaneadhesive tape for example, if the weight of the dispenser is some fiveor six pounds it will function satisfactorily without being secured tothe counter. ()bviously if a wider tape requiring more force to withdrawit'were used, the machine would have to be made heavier.

In all instances the line of pull need not pass through or near thecenter of gravity of the dispenser, but in such cases the moment ofresistance due to the weight of the dispenser should be sufficient toresist the upward pull of the tape. A dispenser presenting the tapeprojecting upwardly so as to be withdrawn by an upward pull isparticularly advantageous for use on store counters and the like, wherethe operator is usually standing It is very easy for a standing operatorto grasp the end of the tape and draw it upward. For many persons theupward pull is also the easiest and most natural movement for the handand arm.

' A'preferred form of the improved dispenser meeting the foregoingrequirements comprises a small and-compact but relatively heavy bodyhaving a chamber therein for receiving and holding a roll of tape, andhaving a tape dispenser opening at the top thereof with means forguiding and supporting the end of the tape in an upwardly projectingposition, the end of the tape lying at or near the vertical axisextending through the center of gravity of the dispenser. The lateraldimensions of the dispenser need be no greater than necessary to providea receptacle for holding a roll of tape of the desired size.

Thus the'amount of space on the counter or table taken up by-thedispenser is a minimum. The weight of the dispenser is made great enoughto resist the pull necessary to unwind the characterof tape designed tobe dispensed therefrom. If the pull is straight upward'iin the line orapproximately the line of the center of gravity, the entire weight ofthe dispenser is availed. of. The roll of tape is preferably completelycontained within and protected by the.

In this case the whole weight of the dispenser is effective body of thedispenser, so that it is not subject to injury by being touched orstruck by any object which would damage the roll and prevent unwindingof the tape therefrom. Presenting of the end of the tape in an upwardlyprojecting direction also permits and in effect forces the operator tograsp the same by applying the finger to the end of the tape in such aposition that the piece. of tape dispensed will project from the end ofthe finger in line with the finger. This permits the tape to be appliedto the surface to which it is to be attached by merely crooking thefinger and pressing the thumb on the back of the ,free end of the tapeso that it may be and ready application of very short pieces of tape,which is often desirable. The dispenser is preferably provided with acut off blade projecting upwardly alongside the upwardly projecting endof the tape, and owingto the manner of withdrawal of the tape whileattached to the end of the finger as described, thetape maybe drawnsharply down across the cut off blade in such a way as to be severed inthe most effective manner. The cutting off over such a verticallyprojecting blade results in a sharp, quick cut and does not permit thetape to be pulled out during cutting. There is thus no overfeeding orcutting of the tape on adiagonal line, as often occurs with cut offblades otherwise located. Desirably the dispenser may include ameasuring slide, the upper end of which constitutes the cut-off bladeand which is drawn upward with the tape for'a limited distance, therebydetermining the length of. the piece of tape dispensed. V

While all of the above features are included in the preferredembodiments of the invention, in some instances one or more .of suchfeatures may be'dispensed with, or embodied in dispensers of differentconstructions.

The dispenser ofv this invention overcomes numerous disadvantages oftacky tape dispensers of thetype at present mostv widely in use in whichthe roll of tape is mounted ina trough with the upper part of the rollexposed, and in which the tape is unwound by lateral pull which tends toslide the dispenser along the counter or support on which. it rests.Such dispensers usually necessitate the use of both hands, one to holdthe dispenser and the other to pull out the tape-Furthermore the pullingof the tape in a lateral direction requires space in front "of thedispenser for movement of the operator's hand, so that considerable roommust .be pro vided in order to use the dispenser.

Another disadvantage is thatin mostprior dispensers the cut off blade.is mounted in a horizontal plane so that the tape has to be pulleddownwardly below the horizontal in order to be torn off. As this is anawkward movement for. the operator to make the tendency is to'bend thetape over the tear off blade as little as possible. This results inimperfect cutting action and frequently more tape is pulled off than isdesired in the attempt to draw the tape over,the blade. Another.disadvantage in existing machines whichis overcome in the. presentinvention is that in machines in which the tape is withdrawn laterallythe end of the tape from which the piece :has been dispensed issupported on top of the. cut off blade, so that the tape must-be graspedby the operator by inserting the finger 2-. This is important because ifa roll of pressure. sensitive tape is pressed uponor dented it willsometimes causethe layers of tape t adhere so.

tightly to one another that the tape cannot be unwound without tearing.I

Means are preferably provided for guiding and measuring the tape to bewithdrawn. In the construction shown these means comprise a slide in thefor m of a plate 58 which has a tape supporting flange or plate 58 atright angles thereto. The plate 56 is mounted for movement in the.direction in which the tape is to be withdrawn.

In the construction shown the plate 56 is mounted forivertical movementand is provided with a pair of slots 62. and 64 which receive and ar eguided by the studs 56 and 36 respectively. The tape supporting flange58 is preferably at least as wide as the widest tape which is to bedispensed bythe machine and it .is placed to travel close to theadhesion roller 44 but spaced therefrom sufliciently t permit the tapeto pass between the flange and roller. Whenthe slide is mounted formovement in a vertical direction, as shown, the top part of the plate 56and of the flange 58 normally project a short distance above the top ofthecasing, as shown in Figs. 1 and 2. I The projection should be justenough to permit the operator to grasp the top of the slide and the tipend of the tape between the thumb and forefinger, so that he maywithdraw the tape and slide together as shown in Fig. 3. As thenon-adhesive side of the tape faces the flange 58 the adhesive side ofthe tape is exposedin front of the flange where it will adhere to theoperators forefinger when the latter grasps the top of the tape andslide.

In order to enable the operator to get a better grip on the slide thelatter maybe provided with knurling or ridges, as indicated at 68 inFig. 2.

By. providing means for limiting the upward movement of the slide it ispossible to dispense a,

measured amount of tape because the tape and slide aredrawn up togetherand only so much tape will be drawn out as is permitted by movement ofthe slide. As illustrated the plate 56 is provided with a stop flange10, the corner of which will come up against-the surface 12 in thecasing, thus limiting the maximum movement/of the slide. When it isdesired to dispense shorter lengths of tape means may be provided forlirn iting the slide to a shorter movement. As shown such means take theform of a stop ,pin 14 which may be placed in a hole I6 win a hole 18'.In cases where it is desired to serve the maximum length the pin can beremovedand placed for safekeeping in a hole 80 where it will be out ofthe way of the flange '10.

The top edge of the plate 56 is preferably sloped as indicated at B2,and merges at its upper.

end with the top of the flange 58. This upper edge of the slide plateforms a convenient guide for the operatorsfinger and assists him inlo'-' eating. it properly in engagement with the end of the tape. Whenthe operator releases his grip on the flange 58 the slide will dropbackto its lower position by gravity. 90 may be provided to assist thereturn of the slide. .The-spring 90 is shown as anchored at one end to apin 92 in the casing wall and passed under sheave 94' mounted on thepivot 96 set in the casing wall, and the other end of the spring isattached to the stop flange 10. This permits the use of a long springand gives flexibility and smoothness of action without danger ofoverstressing the spring.

If desired a spring 8, The slide passes upwardlythrough arectangularopening indicated at 10min the .top of the casing.Pre'ferably a .pair of bosses 102 are formed on;the casing in front ofthe slide at each forward corner of. the opening. These two bossesprovidea space between them which assists in-guiding the thumb of theoperator into engagement' withthe ribbed surface 68 on the front of theflange 58. The outer surface'of the; s n betwe random Iron fe o ses waspreferablysmooth an unobstructed.so that the operatorfs thumb will slideeasily into-position without encounteringany obstacle or roughness."

In theform ofdispenser; shown in Figs. 1 to 9, thecasing-isofballordome, shape so that its upper portion is rounded. from allsides towardsthe'tapedispensing slide. This makes it particu-' larly easy-for, theoperator to locatehis hand in,

proper position forgrasping the. tape as he can slide his. fingers alongthe curved or sloping -'sur:- faces; and bring them readily 'to the endof the tape andslide. ,Thereis no obstruction either in front. orrearof-the slide to the freemovement of the fingers and it isunnecessaryfor the operaton-tol reach his. fingers-down into. a recess or openingvordergto :get hold of the tape and slide. a V

In operation it is usually des'r'ableto place the dispenser. on thecounter, or table with the'side of;the flange .58 away from thetapefacing the operator. .,The tape is thus on-theside of the flange :58furthest from .the operator with the,

adhesive surface facing :away from, the operator.

The operator then reachesyout his'hand for the top of the machine, asshown in Fig. 1,1lays his forefinger upon theexposed adhesive surface ofthe tape, presses his thumb, against thevribbed side of. the flange 58and -applies'sufflcient pressure so that he grips both-the end of ithe:tape and. thelcflange. vrI-Ie now draws the tape and flange upwardly-asfar asthe setting of the stop meanswill' permit, this being the positionshown irnFig'; .31.- He thendraws back his thumb,

as shown in Fig. 5. whereupon the slide will im-..

mediatelyldrop down into' retracted position. At this time, however, thetape is firmly adheredto the operators: forefinger; sothat-the' tapestays in its projectedposition while the slide returns;

This leaves exposed a measured length. of tape? which 'is to bedispensed. r

' For severing the tape" the top of th'eflange' carries at its upper enda severing blade .106, the upper edge of which is preferably serratedasiindicated' at I011 It is desirable -.to form the top of the slide andseveringablade in such alway' as'to avoid sharp corners on the severingblade which'might cii t'or scratch the fingers. ofthe operator ifcarelessly applied when grasping the tape and'slidei As illustratedthe'topv ofwthe slide is" out outas indicated-at H38 so'astoleaveprotec'tivecorner tabs 109 at each end of. the s'ev-1 ering bladeextending up as J high or slightly.

Owing to the fact' tliat the*blade projects-up wardly, it isasy for theoperator to draw the tape sharply down and across the blade so as to geta good cutting action. The tape can in effect be folded down over theblade so thatthe actionis almost like that of'a paper cutter when usedto'cut a folded sheet. This cutting action The severingis done by the ismuch better than is obtained where the blade ishorizontal or in such aposition that the tendency is to merely pull the tape against the bladeat a slight angle to the plane thereof. Under such conditions the tapemay be pulled out to some extent at the same time that it is being cut,thereby giving a diagonal cut or tear. With the upwardly projectingblade of the present invention there is little danger of doing this.

Another advantage of an upwardly projecting tear ofi blade is that thecutting is done with the downward motion of the hand, which is in effecta return motion following the upward movement of the hand in drawing outthe tape. The feed carries the hand straight up and the cut carries itback almost straight down, and towards the package or article to whichthe tape is to be applied. This combination of movements is aparticularly natural, easy and efficient one for the operator.

The operator having severed the tape as described now has a short stripof tape adhered to his forefinger and extending in the same directionlongitudinally as his forefinger. Only a small end of the tape adheresto the forefinger, thus leaving a projecting end of gummed tape forapplication to the article. Owing to this method of applying the fingerto the tape the total length of tape can be very short, not more thanhalf or three quarters of an inch, for example. The tape is now in mostconvenient position for application to the article, as all that theoperator has to do is to crook the end of his finger, as shown in Fig.8, and lay the end of the tape against the article. His thumb is now injust the right position to press down the end of the tape and cause itto adhere to the article, and the operator can now readily manipulatehis finger and thumb so as to' shown in Fig. 9. Thus the operator maywith one hand pull out a measured length of tape, sever the same andapply it to the article. This leaves his other hand entirely free tohold the article and in the case of a wrapped package for example he canhold the wrapper in place ready to be sealed. Also if he is using ashort piece of tape to attach a card to a record sheet for example, hecan hold the card and sheet in proper registration in one hand whiledispensing and aflixing the short piece of tape with the other hand.

In occasional instances it may be desirable to withdraw the tape withthe thumb and use the. thumb to apply the tape to the article using theforefinger to press the tape down.- In this case it is only necessary toturn the dispenser 90horizontally so that the adhesive side of the tapefaces the operators left.

' Figs. 10, 11 and 12 show a modified form of dispenser embodyingsome ofthe features of the present invention. The dispenser shown in thesefigures does not provide for measuring the length of tape withdrawn butpermits the tape to be pulled in an upward direction and torn off andapplied in the manner already described. The judgment and eye of theoperator are relied upon to secure the dispensing of a piece of tape of.

proper length. Inthis form of machine the tape is drawn from the roll 40and passes over a guide roller I60 which engages the non-adhesive sidetapein an upright position and preventit from dropping back. into themachine. The end of the tape lies against a. backing plate I62 whichcarries a cut oif blade I64 the upper edge of which is preferablyserrated as indicated at I66. The corners of the backing plate maydesirably extend slightly higher than the serrated edge as indicated at"$1, so as to protect the operators fingers. 'An

opening is provided through the backing plate and cut-off blade topermit the thumb of the operator to contact the non-adhesive side of thetape. As shown this opening is provided by a notch 1-68 in the backingplate and hole H0 in the cut-off blade. The top of the hole H0 is nearthe serrated edge of the cut-ofi blade so that only a narrow bridge H2is left between the edge of the hole and the serrated cutting edge. Inthis form of dispenser the cut-01f blade and backing plate arestationary, the backing plate being secured to the frame in any suitablemanner, as by means of rivets H4 passing through holes in an ear I15 onthe backing plate. The backing plate projects upwardly from the casing,the walls of which slope upwardly towards the front and rear of theplate so as to assist the operator in properly locating his fingers inposition to grasp the tape.

In the operation of the dispenser shown in Figs. 10, 11 and 12 theoperator places one finger over the exposed adhesive end of the tape andpresses his thumb over the hole in the cut-off blade so that it engagesthe back or non-adhesive side of the tape. The operator now moves hisfinger and thumb upwardly, the finger adhering to the tape drawing it upwhile the thumb slides over the bridge in engaging the back of the tapeas it passes from the cut oif blade. In this way the operator may drawout such length of tape as he requires. He then draws the tape acrossthe cut-off blade. He may do this while holding the end of the tapebetween his thumb and finger, or he may move his thumb out of the wayand rely on the adhesion between the end of the tape and the tip of hisfinger for pulling the tape across the cut-off blade, similarly to theac-'- tion shown in Fig. 6. In either event he cuts oh the desiredlength of tape which adheres to the tip of his finger and extendslengthwise thereof, so that it is in a position for immediateapplication to the article to which it is to be applied in the mannershown in Figs. 8 and 9.

1'7. A dispenser for dispensing strips of tape having a tacky side and anon-tacky side comprising a heavy base, means on the base to support aroll of adhesive tape, a cut off blade supported on the, base andprojecting therefrom in an upward direction, and having a cut oii edgeat the top thereof, and supporting means for the leading end of the tapeengaging such leading end by adhesion to the tacky surface thereof, saidsupporting means permitting the tape to be pulled out While in contacttherewith, said supportin means supporting the tape with itsnon-adhesive side adjacent to the side of the cut oii blade.

18. A device for serving strips of tacky material comprising a casingformed of two massive bodies each forming approximately onehaltv of thecasing, said bodies being hollow so as-to provide a. chamber of. suchsize as tocompletely enclose a roll of tacky strip material, means forsupporting said roll inside of said chamber for rotation about ahorizontal axis, said casing having an opening in the top thereofthrough which. the tacky material may be with drawn, said massive bodieshaving bottom sur-v faces adapted to'be; set upon a table or othersupport, and being connected together near-said bottom surfaces by hingemeans pivotal about a,- horizontal axis, said casing being of sufiicientweight to resist the force necessary to unwind the tacky material fromsaid supply roll when it is pulled upwardly through the opening in thetop of the casing.

19.-A device for serving strips of tacky material comprising a casing;in the form of two massive hollow bodies each forming, approxi matelyone-half ofv the casing, one of said bodies carrying means forsupporting a roll of tacky material and. means tor supporting andguiding a-reoiprocating slide, said slide being mounted toreciprocate inand out of an opening in the upper part of the casing, the end of theslide projecting out of the casing when the slide is in its inwardposition, and means in the casing for normally supporting the leadingend of the tacky material in a position to project upwardly through theopenin in the casing along side of the reciprocating slide, so that theslide and tacky material may be simultaneously grasped, said casingbodies being hinged together at their lower ends by hinge means having ahorizontal axis.

20. A device for serving strips of tacky tape including a casing havingan opening in the top thereof, said casing having a chamber in theinterior of suiiicient size to completely enclose a supply roll of tackytape, means in the casing for rotatably supporting said roll of tape,said casing having an opening in the top thereof for withdrawal of thetape, means for supporting the leading end of the tape with its upperextremity projecting upwardly out through the opening in the top of thecasing, a measuring slide disposed in a generally upright attitudewithin the casing, means guiding the slide for reciprocation in an upand down direction, said slide having a tape supporting portion at thetop thereof projecting at all times above the top of the casing so thatthe projecting end of said slide and the leading end of the tape may begrasped simultaneously and drawn out to feed tape, stop means forlimiting the distance by which the slide may be drawn upwardly, so thatthe slide may be used to measure the length of tape drawn out, and meansfor severing the measured length of tape, said device being sufficientlymassive to resist by its weight alone the force necessary to be exertedon the tape to cause it to unwind from the supply roll when it is pulledupwardly from the supply roll.

21. A dispenser for dispensing strips of pressure sensitive adhesivetape comprising, a casing,

means in the casing for rotatably supporting a roll of pressuresensitive adhesive tape, said casing having an opening therein, andmeans for presenting an end of the tape projecting out of said opening,in a position for grasping and removal, said tape presenting meansincluding an adhesion roller mounted adjacent to the opening in thecasing and adapted to support the end of a roll of tape by adhesionthereto, said adhesion roller having mechanism associated therewith andis acting directly thereon for preventing free turning of said adhesionroller in at least one direction. i

22. A device for serving strips of tacky material comprising a casingformed of two massive bodies each forming approximately one-half of thecasing, said bodies being hollow so as to provide a chamber of such sizeas to'completely enclose a roll of tacky strip material, means forsupporting said roll inside of said chamber for rotation about ahorizontal axis, said casing having an opening through which the tackymaterial may be withdrawn, said opening being bounded on one side byparts of one of said'bodies and on the other side by parts of the otherbody, so that when said parts are separated, the walls of the openingare spread apart, said massive bodies having bottom portions adapted tobe setupon a table or othersupport and being connected together at saidbottom portions'by hinge means pivoted about a horizontal axis, wherebywhen said casing is set upon a table, gravity tends to hold said massivebodies together in closed position, an adhesion member carried by thecasing adhesively supporting the tacky material 16 in position to bewithdrawn through said opening and tape severing means carried by thecasing for severing the material withdrawn from the supply roll.
